Objects: atmospheric environment, aquatic environment, information systems The aim of the project is the development and adaptation for hydrometeorological research and the solution of current problems of rational environmental management of a complex of atmospheric, marine and hydrological mathematical models with their further integration into information systems for analysis and forecasting of the natural environment. The report presents the results: mathematical models of hydrometeorological processes and the spread of pollutants in the atmospheric environment and surface waters have been improved through the development of new numerical schemes and parameterizations of physicochemical processes. On the basis of the developed models, the mechanicsms of the spread of pollution in the environment were studied, the consequences of the scenarios of the of environmental accidents were assessed, and information systems for environmental forecasting and analysis were developed. Simulation of scenarios of atmospheric distribution of radionuclides as a result of a potential beyond-design accident at the Zaporizhzhya NPP was carried out, and estimates of the possible consequences of such an accident were obtained; the maximum size of the zone in which the fallout of cesium-137 may exceed 400 kBq/m2, which corresponds to the lower limit of justification for permanent resettlement according to the legislative criteri is 170 km. The scenario with a dominant fallout of radionuclides on the surface of the Black Sea as a result of a hypothetical beyond-design accident at the Zaporizhia NPP was chosen. The resulting doses of human exposure from the consumption of seafood in such an accident may exceed the IAEA permissible norm of 1 mSv/year, reaching 10 mSv/year in areas with the maximum density of radionuclide fallout, which indicates Product Description popup.authors Bejenar Roman Vasylovych Brovchenko Igor Oleksandrovich Dontsov-Zagreba Timofey Oleksiyovych Kivva Sergey Leonidovych Kovalets Ivan Vasylovych Kovalets Kateryna Ivanivna Maderich Volodymyr Stanislavovych Maystrenko Svetlana Yakovna Nochvay Volodymyr Ivanovych Polonsky Oleksandr Oleksandrovich Sinkevich Roman Oleksandrovich Sorokin Mykhailo Vasylovych Udovenko Lyudmila Fedorivna Udovenko Oleg Ivanovych Khalchenkov Oleksandr Volodymyrovych Khurtsilava Konstantin Viktorovich popup.nrat_date 2024-01-18 Close
